Introduction
• Dermatological emergencies are those cutaneous conditions that can be life
threatening if not diagnosed quickly and managed accordingly.
• Dermatological conditions with widespread systemic involvement and
complication are the emergencies that have to be dealt with in ER.
• Prompt recognition for appropriate diagnosis and treatment is necessary to
improve a patient’s prognosis and a single decision can make the difference
between LIFE and DEATH.
• Multiple faculties involvement according to the emergency of the condition
is required.

Erythroderma
• Erythroderma is an inflammatory skin disease with redness and scaling
that affects 90% or more of the patients skin.
• Also known as Exfoliative Dermatitis
• Extensive skin exfoliation : 20-30g/day
• 18-20% mortality
• Males affected more (4x)
4
Presentation
• Initial lesions
• Erythema – rapidly progressing later scaling
• Established Case
• Erythema, Scaling and Induration involving >90% BSA
• Ectropion, Eclabium, Everted nostrils and flexion contracture of joints
• Later
• Exagerrated skin folds and shedding of hair, eyebrows, eyelashes and nostrils
• Lymphadenopathy
• Association : Extreme pruritus, Enteropathy,
• Lesion of primary illness
5
Why an Emergency?
• Temperature Dysregulation
• Skin loss and hypothermia
• High Output Cardiac Failure
• Dehydration and Electrolyte imbalance
• Hypoalbuminemia
• Loss of muscle mass
• Thrombophlebitis/DVT
• Infection-both cutaneous and respiratory with pneumonia a major cause
of death

Norwegian Scabies
• Seen in immunocompromised individuals
• begins with poorly defined, erythematous patches that quickly develop
prominent scale
• usually spreads inexorably and may eventually involve the entire integument
• Scales become warty, especially over bony prominences.
• Crusts and fissures appear.
• The lesions are malodorous.
• Nails are often thickened, discolored, and dystrophic.
• Pruritus may be minimal or absent.

• Associated fissures provides entry point for organism
• Secondary infection
• Septicemia
• Glomerulonephritis
• Aesthetic complications

combination regimen for the treatment of crusted scabies:
• Permethrin 5% cream applied every two to three days for one to two
weeks
• and
• Oral ivermectin (200 mcg/kg/dose) given for three, five, or seven
nonconsecutive days depending on severity of infestation
